RRI 6030 kHz Galbeni, Romania, reception near Atlanta, Georgia, USA

This afternoon's reception - no audio decoded, 14.08dB max SNR.

Some problems as the transmission started later than scheduled and some breakdowns during the broadcast.

Reception was better near Boston, 1,480 km closer to the transmitter (see 2nd attachment).

About bad 64-QAM, ask for 16-QAM on MSC

Hello,

Dear Mr. Braccini,

Please be informed that we will take your suggestion into consideration,
and we will consult with the equipment manufacturer about the possibility
of reconfiguring the long distance transmitters.

Thank you and best regards.

This afternoon's reception - no audio decoded, 14.36 dB max SNR.

The problem in decoding is the very high bit rate of 21 kbps and not the 64 QAM.

Furthermore the audio bandwidth used is less than 5 kHz - makes no sense to run such a high bit rate!
